Girl, put your knickers on, tell me your favorite song
You go head, let your hair drown

The story:

After hearing it on the radio for the first time I thought to myself 'Wow that's a bit rude.'
I then heard my mum singing it a few weeks later and explained to her how wrong she was singing it and what the correct lyrics were.
She laughed at me. Lots. And then explained that I was totally wrong
I was only young and a tad deaf though.. :)
